The President of the A.F.L.-C.I.O., Richard Trumka, who flirted with an alliance with President Trump, delivered a searing critique on Tuesday of the president’s first year, saying that he had used the White House “to actively hurt working people” and favor corporate interests.

“Broken promises are bad enough,” Mr. Trumka said during a meeting with reporters. “But President Trump has also used his office to actively hurt working people. He has joined with corporations and their political allies to undermine the right of workers to bargain collectively. He has taken money out of our pockets and made our workplace less safe. He has divided our country, abandoned our values and given cover to racism and other forms of bigotry.”
